On the macro front, the US PCE price index rose 5.4% year-on-year in January, higher than expected a 5% increase, and the personal consumption expenditure price index rose 0.6% from the previous month, the biggest increase since June last year, which led the market to believe that inflation is difficult to fall, and interest rate markets believe that the risk of a 50 basis point rate hike by the Fed's March meeting is rising. Although copper prices were clearly hit by this, the stagflation of the dollar index at 105.32 points stabilized copper prices. The domestic manufacturing PMI in February rebounded to 52.6, the highest since April 2012, and the US ISM manufacturing index rose to 47.7 in February, the first improvement in the past six months.
